Error customer metafield API (Status code: 502)

[H1R0]

Hi!

I'm develop an Shopify App and that app to create a metafield for customers.

However, when I tried to create a metafield using a webhook from one of the stores, I got an error.

If necessary, you can also provide a request header etc.

Thanks!
